Sorry Celeste, notifications weren't sending me e-mails, so I didn't see this until now, which is obviously far too late!
If the texture is in the Meshlab file, it should import fine. You'll probably need to change the bitmap scale manually in Archicad though.
You can manually load the texture file anyway, using the Creative imaging tools to position the origin and rotation of the texture. You'll still have to scale the image in the surface editor.
It is a pain, and actually morphs are easier to mange. The Mesh terrain features are actually broken. The Import mesh from surveyors data is not fit for purpose.
It's better to take a proper weighted triangulated 3d model from another modeller, apply the texture, and import as a morph. The texture comes through properly then.
You can't use the nice mesh editing tools, but you get a much, much more accurate terrain.
What we actually need is a tool which converts a morph to a mesh. That's actually all we need. There are enough tools out there which allow us to get triangulated terrain models without having to build it in Archicad. In fact building terrain in archicad for large sites makes absolutely no sense whatsoever.
I was chatting to Graphisoft Tech people at the AIA convention a couple of years ago, and apparently a much improved mesh tool is coming.
I don't know how much you have worked with meshes, but it's absolutely infuriating.
You move a node and the triangulation recomputes apparently randomly! It's not like a SketchUp mesh or a morph where you can freely move and snap nodes controlling their position in any of the axes.
Where I work, in Wales in the UK we almost never get flat sites, and understanding the topography in 3D is really important. Unfortunately this means I have spent many hours trying to make the mesh tool work effectively, and almost always failing in some measure.
